3. Three people pull on rope attached to a ring. One force Fi has magnitude of 100N and pulls along the positive X axis. The second rope exerts a force F2 of 200N in a direction 45° above the negative X axis. A third rope pulls with an unknown force Fathat causes the ring to remain in equilibrium. Calculate the magnitude and direction of F3.

3. Three people pull on rope attached to a ring. One force F; has magnitude of 100N and
pulls along the positive X axis. The second rope exerts a force F2 of 200N in a direction
45° above the negative X axis. A third rope pulls with an unknown force Fathat causes
the ring to remain in equilibrium. Calculate the magnitude and direction of F3.
4. A gymnast with a mass of 50.0kg suspends herself from the lower end of a hanging
rope. The upper end of the rope is attached to the gymnasium ceiling. What is the
gymnast's weight? What force does the rope exert on her? Suppose that in the above
example, the weight of the rope is not negligible but is 120N. Find the tension at each end
of the rope.
